目前，我国中压配电网的网架优化与资金合理利用，在规划设计中日益凸显。通过对中压配电网接线方式的经济性研究，采用经济、合理的接线方式十分重要。运用一种可调供电面积的分析模型，对10 kV 配电网的接线方式，在不同区域负荷密度、不同变电站容量、综合投资和电价的条件下进行分析，并采用“最小单位负荷年费用法”对中压配电网经济指标进行量化及变化趋势分析。以浙江省丽水市云和县为对象，运用上述方法进行计算和分析。通过计算结果比较，给出经济性最优的接线模式，并找出影响经济性的敏感性因素。

Nowadays,existing problems in middle voltage distribution network planning in China are Network optimization and how to use the fund properly.Through economy study of middle voltage distribution network connection mode,we find that using economic and reasonable wiring way is very important.An area-adjustable power supply model is used to analyze connection modes for 10 kV distribution networks under the condition of different load density in different areas,different substation capacity,comprehensive investment and electricity price.Also use"The smallest unit load annual cost method"to quantify economic indicators of middle voltage distribution networks and analysis it's change trend.Yunhe County (in Lishui City of Zhejiang Province)was chosen as an example to use above method for calculation and analysis.By comparing the calculation results,it can give the economic connection mode.We can both find out sensitivity factors affect the economy.
